The owner of an Arizona gun store said he will not sell weapons to customers who voted for President Obama because “you have proven that you are not responsible enough to own a firearm.”

Cope Reynolds, owner of the Southwest Shooting Authority in Pinetop, Ariz., posted the new store policy in a newspaper advertisement — as well as on a sign posted on the front door.

“If you voted for Barack Obama your business is not welcome at Southwest Shooting Authority,” the ad reads. “You have proven that you are not responsible enough to own a firearm.”

The Southwest Shooting Authority is a family-owned, family-run business that Reynolds opened in 2004. He told Fox News that he’s absolutely serious about the new policy.

“I’m a small business owner,” he said. “If you are dumb enough to vote for Obama again – after four years of this — I don’t think you are responsible enough to own a firearm. I don’t care who it makes mad.”
